thanks in advance,

I would probably stick with the manufacturer's recommendation. I don't think Toyota issued a TSB (technical service bulletin) saying that 5W-20 is OK for that car.
For newer cars, the thinner the viscosity, slightly more is the wear. But since most people don't intend to keep their car for more than 300,000 miles or so, even the thinnest 0W-20 grade should be OK. Also, advanced ZDDP and moly in modern engine oil help protect against wear even when the oil film fails. For older cars, wear can be more abrupt; so, be careful with going to a too thin viscosity.
The main advantage of thinner viscosity is fuel economy. But there is not much difference between 5W-20 and 5w30 -- only about 1 - 2%.
Pennzoil Platinum or Ultra hardly has any advantage over Pennzoil conventional. They are slightly more shear-resistance (slightly less wear because they stay slightly thicker) and they are less volatile (slightly less oil top-offs). Stick with the yellow bottle.
If oil consumption becomes a problem, try switching to 5W-40 or 15w40. It will more than likely be the case for your car now or soon since it's 13-year-old, as the valve-stem oil seals are probably worn or about to be worn. By switching to a thicker viscosity, you won't have to add oil every 500 miles if or when that becomes the case.
